Title: Operation control system for automatic door
Inventor: KOIKE KATSUFUMI
IPC: E05F15/20
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To provide an operation control system for an automatic door, which is suitable for accurately performing maintenance by supplying effective information when the maintenance of the automatic door is performed. SOLUTION: A remote controller 90 transmits a transmission request for requiring transmission of abnormal information together with a code number of an EEPROM (not shown), to a controller 20, and when the remote controller receives the abnormal information, it stores the received abnormal information to the EEPROM (not shown). When an abnormal state occurs during control of the operation of a door by the controller 20, it creates abnormal information regarding the abnormal state and stores the same in an EEPROM 75. When the controller 20 receives the transmission request and the code number from the remote controller 90, the controller 20 collates the received code number with the code number stored in the EEPROM 75, and when these code numbers are the same, the abnormal information of the EEPROM 75 is transmitted to the remote controller 90.

Title: Clock phase fine adjusting circuit
Inventor: UCHIYAMA IZUMI
IPC: H04L25/40
Filed: 1984-07-28
Abstract: PURPOSE:To enable fine adjustment of clock phases by providing an RC circuit and a comparator in a repeater of digital communication and using the junction capacity for the capacity of the RC circuit. CONSTITUTION:When a clock signal of waveform (1) is inputted, rise and fall parts are made dull as shown by a waveform (2). This is compared with reference voltage Vref by a comparator COMP and a signal of a waveform (3) is outputted. Here the time constant due to internal resistance Re of a transistor Q and the junction capacity C can be changed by changing the terminal voltage of junction capacity of an integrated circuit, and accordingly, its phase difference can be ajusted. Thus, as clock phases can be adjusted finely, the clock signal can be adjusted most suitably in a superhigh-speed repeating circuit.

IPC: B23Q5/44
Filed: 1994-06-17
Abstract: PURPOSE:To surely prevent rotation of a nut member by providing such an arrangement that a braking piece is brought into contact with the nut member at a position which is deviated from a line connecting between the axis of the nut member and the pivotable fulcrum of a swingable member in a direction reverse to a rotating direction in which the nut member should be restrained. CONSTITUTION:When a drive shaft is dropped by its own weight, a nut member 10 is to be rotated clockwise. However, since a brake piece 29 makes contact with the nut member 10, rack teeth of the brake piece 29 are engaged with external teeth 12a, 12a of the nut member 10, and further, counterclockwise torque is applied to a swingable member 28 through this engagement. With this arrangement, the brake piece 29 is to wedge toward a line connecting the axis of the nut member 10 to the rotational center of the swingable member 28 so as to boost the brake force due to the so-called self boosting action, thereby the nut member 10 is not rotated so that the drive shaft 2 can be prevented from dropping.

IPC: G11B17/04
Filed: 1982-09-10
Abstract: PURPOSE:To obtain a reproducer of a recording disk with a simple constitution which can be driven by a miniature driving source, by using a clamper interlocking a lift mechanism to generate the intensive driving power in a clamping state. CONSTITUTION:When a traveling matter 6 is driven left for reproduction, the engagement of a power increasing mechanism 25 due to an engagement part 21 unified with the matter 6 is released. Then an arm 36 and a lift cam 35 are turned clockwise via an arm 39. As a result, a lifter 40 moves down and at the same time a cam plate 46 is turned by the arm 36. Then a lower clamper 17a of a clamper 16 moves down to release the clamp of a recording disk 1. The clamper 16 generates so far the intensive driving power with the elastic power of a spring 52 via a wire rope 50. Then, the disk 1 is put on a turntable 19 and reproduced. In such a way, the large driving power is not needed since the disk 1 is clamped so that no effect is given to the pull-out of a protecting case. This produces a reproducer of a recording disk with a simple constitution which can be driven by a miniature driving source.

Abstract: PURPOSE:To obtain a stable pulse forming circuit by during a transistor TR, which compensates a variance of temperature of an output TR, with a constant current source where a variance of power source voltage and a variance of temperature are compensated. CONSTITUTION:A constant current source 10 where a variance of power source voltage and a variance of temperature are compensated is connected to a resistance 11 and the base of a TR13 constituting an emitter follower.
